The picture quality is okay - Microsoft LifeCam NX-6000 a decent price for a webcam with a plastic lens, but at that price, and at that moment in time, it must have a glass lens. But Justin Yu properly - autofocus is very painful, and should be disabled in software. I had two long conversations with technical support from Microsoft, while more knowledgeable and conscientious support as a rule these days, they do not know about the problem. They finally called me a third time, and told me they were running tests and experienced the same problem. Apparently a few months later, he has not been resolved.
Bottom Line: I buy a Microsoft LifeCam NX-6000 the best price, he returned and bought a Logitech C905. LifeCam physically better developed - it has a small clip and well-positioned wire, which does not bother not with the movement of the camera - but Logitech has a glass lens, which gives much better image. I had a little problem with the flickering image, but download the new software and that seems to have fixed. Unfortunately, I have Microsoft LifeCam NX-6000 e money clip and cable configuration is much more complicated than the LifeCam. This is an ongoing issue with Logitech webcams, someone at Logitech to go back to school design.
